/* ===== 進め方（PROCESS）=====
   ------------------------------------------------------------
   HARC のサイトに置いた「このサイトをつくった人」区画から、
   中身と動きだけを持ってきて、見た目はこのポートフォリオに作り直したもの。

   ★向こうの配色（紺＋金）はひとつも持ち込んでいない★
     金 --gold-*        → var(--accent) / var(--accent-light)
     紺 --navy-*        → var(--bg) / var(--bg-2)
     細線 --line-soft   → var(--border)
     角丸 4px           → var(--radius)（このサイトのカードと同じ16px）
     ラベル --font-ui   → var(--font-mono)
   面・角丸・枠線・近づくと光る出方は、このページの .q-card / .service-card と揃えてある。

   ★動きの作り（向こうから持ってきたのはここ）★
   ① 連続と離散を分ける
      左のレールだけがスクロール量に連動して伸びる（連続）。
      段の中身は一度だけ、部位ごとに時間差で入る（離散）。
      文字までスクロール連動にすると、動かすたびに全文字の描き直しが走ってがたつく。
   ② 1変数駆動
      段ごとに --lit（0→1）が1つ切り替わるだけで、
      番号・見出しの1文字ずつ・本文・タグ・節点・光の帯が全部そこから出る。
      途中で止めても絵が破綻しない。
   ③ 動く距離を部位ごとに変える
      全部同じだと1枚の板が動いたように見える。見出し40px → 本文60px の階段にしてある。
